Crazy as it is seems, but I don't think we will ever see someone on daytime in the league of Oprah ever again. I would love to be proved wrong though. The daytime landscape is different from what it used to be; streaming and social media have taken away daytime television's relevance since you can get entertainment and infotainment anytime in the palm of your hands. Big-name media giants have all tried to replicate the magic with already-established personalities like Anderson, Meredith, Katie to lackluster results.
With the cable industry being a former shell of itself, I totally see broadcasting going to the wayside eventually and the local news industry evolving to meet customer demand on other platforms. I think that this is the reason why you are seeing more newscasts these days rather than stations investing in a talkshow, it's just easier and affiliates are preparing for a time when their audience will more likely see them on an app, social media or on their Roku box. When we get to that point, are network affiliations be of importance? If you ask KTLA, the answer is "not anymore".
